The country park's website explains that the reservoir was constructed in 1871 to supply water to factories in nearby Langley Village. The 1897 OS map tells a slightly different story as what was then called Teggsnosewood Reservoir is labelled as belonging to Macclesfield Corporation Water Works, suggesting that it was built mainly for public supply. There is a slightly unusual arrangement with this and the adjacent Bottoms Reservoir discharging their overflows into a combined, small reservoir or stilling basin.
